In the U.S., African Americans experience significantly higher rates of PTB compared to non-Hispanic Whites. PTB disparities have been linked to social determinants of health (e.g., socioeconomic status, discrimination). However, the biological underpinnings related to these associations are unclear. DNA methylation (DNAm) is subject to environmental influences, and DNAm modifications are known to affect gene expression. Using a multi-omic approach, we examined differences in combined DNA methylation (DNAm) and messenger RNA (mRNA) transcriptomic data from 20 pregnant African American women (12 PTB; 8 term birth) early in pregnancy (8-18 weeks gestation). We found that the <i>HLA-</i><i>DQB2</i> gene was both differentially methylated (cg12296550; <i>p</i> = .02) and differentially expressed (<i>p</i> = .014; log2FC = 2.5) between women with PTB and term birth. Gene expression analysis showed <i>HLA-</i><i>DQB2</i> and <i>HLA-</i><i>DRB4</i> (<i>p</i> = .028; log2FC = -3.6) were the two most highly expressed genes. <i>HLA-DQB2</i> expressed higher in PTB and <i>HLA-</i><i>DRB4</i> expressed higher in term birth. However, no genes remained significant (<i>p</i> < .05) after Bonferroni correction. <i>HLA-</i><i>DRB4</i> and <i>AKR1C1</i> were identified as a potential biomarkers in dimensionality reduction models and are also important to immune function and allogenic breakdown.

While research has shown that microRNAs are an important component of wound inflammation, few have explored the role of microRNAs (miRNAs) in the healing of CVLUs. This scoping review examines miRNAs in CVLUs and the association with wound healing. <b>Methods:</b> In December 2023, we searched MEDLINE/PubMed, Embase, Scopus, and CINAHL for studies published in 2013-2023 examining miRNAs in CVLU healing. <b>Results:</b> Six studies met inclusion criteria. MicroRNAs were extracted from various specimens including serum, skin biopsy samples, and adipose tissue-derived mesenchymal cells from individuals with CVLUs. Overexpression of miR-221, miR-222, miR-92a, and miR-301a-3p hindered angiogenesis, while overexpression of miR-296, miR-126, miR-378, and miR-210 facilitated angiogenesis. Overexpression of miR-34a/c, miR-301a-3p, miR-450-5p, miR-424-5p, miR-516-5p, and miR-7704 increased local inflammatory responses and inhibited keratinocytes proliferation, impairing healing, while overexpression of miR-19a/b and miR-20 downregulated keratinocytes' inflammatory response, promoting healing. Downregulation of miR-205, miR-96-5p, and miR-218-5p enhanced cellular proliferation and promoted wound healing. Downregulation of miR-17-92 was linked with impaired healing. <b>Discussion:</b> MicroRNAs play a role in regulating angiogenesis, inflammatory responses, and cell migration in chronic-wound healing. However, studies of miRNAs in CVLUs are limited and lack a standardized approach to measurement and quantification. Further research is warranted to elucidate the mechanisms underlying microRNA involvement in CVLU healing to better understand the pathophysiology and for the future development of targeted therapies.</p>","PeriodicalId":93901,"journal":{"name":"Biological research for nursing","volume":" ","pages":"339-351"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142482956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
